Problems solved by technology

[0003] The existing technology only adds an entry password lock to the application program. When the third-party application program starts the application program by using the function instead of the entry form, the password lock has no way to prevent the third-party application program from starting the application program. program, which is prone to leakage of user privacy data

Embodiment Construction

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] refer to Figure 1 to Figure 2 , Figure 1 to Figure 2 It is a flow chart of three implementations of the application program encryption method of the present invention, including:

[0049] Step S101: Obtain the encryption password of the application program that needs to be encrypted.

[0050] The way to obtain the encryption password of the application that needs to be encrypted can be: ask the client to enter the encryption password, and then receive the encryption password entered by the client; or, the machine directly encrypts, and then the machine can let the client know the encryption password through other methods .

[0051] Specifically, step S101 may include substep S101a and substep S101b, the contents of which are as follows:

[0052] Sub-step S101a: Prompt the user to input the encryption password of the application program th...

Abstract

The present invention discloses an application encrypting and decrypting method and device. The encrypting method includes: obtaining an encrypting password of an application required to be encrypted; obtaining an application package corresponding to the application required to be encrypted; and according to the obtained encrypting password, encrypting the application package, so that password verification is required when a first operation is performed on the application. By means of the aforementioned manner, the method and device of the present invention can prevent an unauthorized user or a third party application from accessing the encrypted application.

Description

technical field [0001] The present invention relates to the technical field of encryption and decryption, in particular to a method and device for encryption and decryption of application programs. Background technique [0002] With the popularity of the Android system, users have gradually increased their requirements for security and privacy. Currently, Android applications provide private data in mobile devices in a functional way, such as contacts, text messages, call records, and location information. [0003] The existing technology only adds an entry password lock to the application program. When the third-party application program starts the application program by using the function instead of the entry form, the password lock has no way to prevent the third-party application program from starting the application program. program, which is prone to leakage of user privacy data. Contents of the invention [0004] The technical problem mainly solved by the present i...
